Urban dog (l) and vixen (r) Fox, by Garden BirdWatcher Peter Allan

It's National Mammal Week!🐾

Red Foxes are on the rise in urban gardens! These adaptable mammals are now found in around 1 in 4 UK gardens.

Did you know GBW also monitors mammals?
Start your list today and help us find out how they are using your gardens.

The graphic displays four images of Puffins showcasing the different recording units for them on SMP surveys. These are IND (individuals on land at the colony), AOB (apparently occupied burrows), SEA (individuals on the sea adjacent to the colony), and AIR (individuals flying over the colony).

Puffin colony count surveys are recommended from April 30th. Multiple survey methods and recording units can be used to monitor them. Take a look at the graphic below to visualise the different units! ⬇️ #seabirds @btobirds.bsky.social @jncc.bsky.social @rspb.bsky.social

A map showing the migration of Cuckoo Jim from the UK to Africa and back again, with his current location in the UK. A headshot of Cuckoo Jim features, alongside the wording: After making his way steadily north through France, Jim launched across The Channel from Bayeux and arrived on the coast near Worthing on 16 April! From here, he headed to West Sussex, and is just 7 miles from where he was tagged last May.

It is a very interesting one with Willow Warbler. They are now becoming comparatively scarce in Eastern England where BTO HQ is. The whole population seems to be moving northwards and westwards through the UK. It would be a shame to lose them in the southern and eastern UK! David W, BBS Team

An image of a Jay is shown. It is a pink bird with a black moustache. It has blue panels on its wings. A map of England is shown. An arrow shows that Jay declined across the country by 11% 1995-2024. A map of Scotland is shown. It states that Jay increased by 479% across the country by 479% 1995-2024. The title says: ‘Jay trends’. The BBS logo also features a drawing of a Goldfinch.

(2/) Both of these species are showing signs of decline across England. However, they are both increasing in Scotland. What could be behind this change in fortunes between the south and the north of the UK?

A map of Scotland is shown, with an arrow that says this species increased by 55% across Scotland between 1995-2024. The title says: ‘Bullfinch trends’.

1/The decline of specialist butterflies and the diversity that goes with it is a damning indictment of the state of our countryside.

David from the BBS Team did his ‘Early’ visit to his BBS square in Cambridgeshire this past weekend. Despite (almost) falling in a hole, watch this video to see just how much fun he had whilst he was out surveying. @btobirds.bsky.social @jncc.bsky.social @rspbscience.bsky.social #Ornithology

The graphic shows a Puffin with its English and Latin names (Fratercula arctica). There is a key facts box on the graphic that covers their wingspan, lifespan, diet, breeding behaviour, seasonality, and UK breeding abundance.

Perhaps our most familiar and charismatic auks, these bright-billed burrow nesters certainly catch the eye!

If you like bioacoustics, you will love this issue of Bird Census News. It also features the work of @bbs-birds.bsky.social volunteers who are putting out PAM recorders on squares in Scotland, with the aim of seeing if PAM can augment traditional monitoring, especially in hard-to-reach places.

A Green Woodpecker is shown. It has a green body, a red cap, a black head and a grey face. It is perched on the ground facing right. A map of England is shown, along with a down arrow that states that this species declined by 35% 2014-204. The title says: ‘Green Woodpecker.’ The BBS logo also features a drawing of a Goldfinch.

(3/) The possible reasons why Green Woodpeckers are declining in England are currently quite challenging to determine. It may be related to the availability of food, but more research will need to be done to prove this.

(1/) It’s hammer time! Great Spotted Woodpeckers continue to increase across the UK. This distinctive species is even being seen more regularly in Northern Ireland, where it used to be very scarce. @btobirds.bsky.social @jncc.bsky.social @rspbscience.bsky.social #Ornithology #CitizenScience

4/ On the other side of the coin, Goldfinch has increased markedly in all parts of the UK, and has been a beneficiary of garden feeding. However, at least in Southern England, there are signs that this species is either stabilising or even beginning to decline itself.

A male chaffinch sits on a twig. To the right a BBS index plot showing an increase from 1994 to 2007, similar to Greenfinch, but then a rapid decline of 50% in the last 10 years, and which started slightly later (~2012/13). As above, there is a map of England behind and a title 'Chaffinch: England'

3/ But just because Greenfinch might be turning a corner, doesn't mean the problem isn't there. Chaffinch has declined by 50% in the last 10 years, it too having declined due to Finch Trichomonosis and that decline continues...

2/ @bbs-birds.bsky.social data shows that Greenfinch in England declined by 66% 2008–2018, mainly due to the disease Trichomonosis. Recent advice from ‪@rspb.bsky.social‬
bsky.app/profile/rspb... is based on a wide range of evidence, including BBS. However, are there are signs of a recovery?
